AUT 101-Chapter 4 Flashcards
As the piston travels upward, the air-fuel mixture is compressed in preparation for burning. Just before the piston reaches the top of the cylinder, ignition occurs and combustion starts. The pressure of expanding gases forces the piston downward on its power stroke. When it reciprocates, or moves upward again, the piston is on the exhaust stroke.

How do flywheels store energy?
With such a high-speed flywheel, safety considerations become hugely important; the flywheel is fitted inside a super-sturdy carbon-fiber container to stop it injuring the driver if it explodes. (Some forms of KERS use electric motors, generators, and batteries to store energy instead of flywheels, in a similar way to hybrid cars.)
